[Farrell In Vancouver]

During the holidays, I will be visiting my Sis and Brother in law. He has a rebuilt engine now resting in the frame, that is very tight to turn. I wanted to build a starter plate crank I've seen on this board where it is installed in the starter mount and provides a place to ratchet the flywheel using the mechanical advantage of the ring-gear.
Now here's the catch, this is an early engine equipped with a multi-plate clutch. I have some early starters with the narrow shaft, but they are hard to come by. I have more later style starter parts to use and they are a lot easier to find. The starter gears are smaller on the early shaft than the late.
I am wondering if I build on out of the late parts, will it work on a multi-plate ring gear? I do not want to waste anything needlessly.
Thanks in advance!
